Chapter

Coal production at the Miike mine was 14 tons per labourer in June 1958, but this was increased to 44 tons per person as of October 1963. Mined coal was transported by a belt conveyor system, leading to an increase in coal production. In 1958 over 6,000 tons per day left the mine, rising to over 10,000 tons in 1962 and 13,000 tons by October 1963.
